1. INTRODUCTION
This letter report covers a variety of cement-based grouting technologies, both national
and international, that may be applicable to Westinghouse Hanford Company's Waste Receiving
and Processing-(WR-AP) Shred=GTout eaort. iivxAP's mission is to process past and currently
generated solid low-level (SLLW), mixed (MLW), and transuranic (TRU) waste at the Hanford
site, Richland. Washington. As this is an internal letter report, no background on WRAP is
provided.
The waste to be processed by WRAP has been generated in defense related efforts and
are,-in zrtanycases,vnique-to this industry.- tiowever, the commercial sector of the nuclear
industry has developed, both in the United States and abroad, grouting technology that, with
- modification, is applicable to WRAP ( i.e., the solidification/stabilization of spent ion-exchange
resins).
Information is provided on USDOE grouting efforts at Oak Ridge, Tennessee
/Hydrefracture at ORYL and the Sludge Fixation Faciliry at the K-25 Site), PREPP at INEL,
Saltstone at SRS, West Valley, NY, and Soilcrete at INEL A brief description is given of the
Rocky Flats plant inert carrier process. A manual laboratory process for making pellets of TRU
waste is mentioned. It should be pointed out that little work has been reported on grouting
shredded solids as is the mission of WRAP's shred-grout module.
Most of the international information reported is from nuclear utilities. It is difficult to
obtain information on defense related efforts in countries that have nuclear weapons programs.
such as the United Kingdom (UK), France, and the USSR. West Germany (now just German,v)
has a small shred-grout facility at NUKEM's Hanau plant. This operation was covered in
R. ::'otojack> 1»^ trip report and will not be repeated here.
It is noted that the majority of grouting information reported in the open literature
addresses the use of cement-based materials (i.e.. grouts) to solidify liquids and slurries. Most
